Abstract
Population-genetic analysis of hybrid populations of green frogs from the Dnepr basin demonstrated limited gene introgression in diploid hybrids in addition to semiclonal reproduction, which is typical for Rana esculenta hybrids. Introgression is largely confined to the Ldh-B locus: the gene of R. lessonae is introduced into the R. ridibunda genome. This phenomenon is unstable as it is geographically restricted and absent in populations of the E-L type.
摘要
对第聂伯河流域绿蛙杂交种群的群体遗传学分析表明，除了半克隆繁殖（这是食用蛙杂交种的典型特征）外，二倍体杂交种中的基因渐渗有限。基因渐渗主要局限于乳酸脱氢酶-B位点：莱氏蛙的基因被引入到食用蛙的基因组中。这种现象不稳定，因为它受地理限制，在E-L型种群中不存在。
